CNotes was developed as part of the "Joomla extension development masterclass" (http://dothewebinar.com) in July 2012. Together with our students we've explored the Joomla framework and have build something that is hopefully useful to you as well!
* add private notes on every page of the site (provided that the cnotes module is published on that pages :))
* notes are added without page refresh (long live ajax!)
* user can add/edit/delete his own notes in the frontend
* administrator can view/edit/delete notes in the backend

In fact when I was hesitate to download it or not, I found the the support team was asking me if I had any questions via Chatbox via web! I asked and got immediate feedback.
After I downloaded and installed, it worked like a dream. I requested if I can be contributing my mother language to this great component and was shown shortly to transifex where I can help with my own language, from where I found other people are working on it too, which explains it's a well-known one.
Great support and product, thanks!
You can use it to take notes as a developer but also as a Marketing or R & D people.
It will be very efficient in Intranet. And you can create in Joomla a common user per Department to let people of your staff to take a view at shared notes.
They are also plenty more possibilities that the fine settings of some permissions allows.
The only reason I am not giving 5 stars to this extension is that the component could be improved in terms of confidentiality for preventing the super admin to see some very confidential notes like a CEO or Top Level Management's note.
But this is very complex to do and the component is Free!
So thank you Compojoom for making it available for us.
